Special CJM Azad Singh fixed for tomorrow the hearing of an application moved by UP ATS seeking his police remand for 10 days.
In the application, the UP ATS said since the accused has admitted that he was a spy of the Pakistani intelligence outfit, his custodial interrogation was required.
Aftab was arrested from Faizabad, 120 km from here yesterday by the UP ATS, which in a joint operation with Maharashtra Police nabbed two more suspects from Mumbai.
They were part of an espionage racket linked to the Pakistan High Commission in New Delhi.
